Questions: Girl's Behavior

i'm an assistant professor at a university, and i'm the research supervisor of a female student whose behaviour has confused me. the girl is usually distant, and i have scolded her very severely at times to which she just rolls her eyes or frowns but always stays quiet. recently, i gave her a research task to do which coincided with her exam schedule, when i insisted that the task has to be completed at any cost , she got a quite rude and said that she WILL NOT do the task since its not part of her research (Although it was) and that she has exams, i asked her to hire an attendant to do the job, the attendant asked for more money than she could give so she got rude with me and she that she can't do the task at the moment but the task was urgent. i am also her teacher for a subject. i was very mad at her for her behavior. the next morning she came with the amount and said that its for the attendant to do the task, but i refused, upon multiple refusals to take the money, she started crying hysterically and she starting shaking. i told her its okay i'm not going to fail you, but she was crying like somebody had died and said ' I'M SORRY SIR... I'M CRYING BECAUSE I FEEL BAD THAT YOU FELT BAD. I GOT FRUSTRATED. I'M SORRY.' she went on crying and refused to leave unless the money was taken from her. then i took the money and she left. i couldn't understand the reason why she was crying like that just because i felt bad? is she attracted to me? is she in love with me? or is she just afraid of failing? PS. the girl is very pretty.

Think like you two are both in the same area or whatever, like a workplace setting or whatever other setting in public but two strangers. If she initiates conversation or wants you to come closer while she's doing a task or multitasking let's say on her phone, so she's not having a direct as such conversation with eyes or whatever, but she's chatting while doing tasks or doing her phone activity, is it being flirty or just chatty. Especially if her opening line was "how are you?" 😄 And asking it in a foreign language and asking if I know what it means? Lol. I didn't know at the time, I was abrupt and said No and I just pissed off lol back to my own activities.
